2003-11-17 Jakub Jelinek <jakub@redhat.com> * posix/regcomp.c (optimize_utf8): Optimize multi-byte chars as well. * posix/bug-regex20.c (tests): Add new tests. Multi-byte char followed by dup operator is expected to be optimized. * posix/regexec.c (check_node_accept_bytes): Move nrules and j variables to the block where they are only used, initialize nrules only immediately before using it. 2003-11-15 Andreas Jaeger <aj@suse.de> * sysdeps/x86_64/fpu/s_scalbnl.S: New file. * sysdeps/x86_64/fpu/s_truncl.S: New file. * sysdeps/x86_64/fpu/s_nearbyintl.S: New file. * sysdeps/x86_64/fpu/s_floorl.S: New file. * sysdeps/x86_64/fpu/s_ilogbl.S: New file. * sysdeps/x86_64/fpu/e_remainderl.S: New file. * math/libm-test.inc (floor_test): Test also ±0.25. (ceil_test): Test -0.25.
